Get Adaptive’s intelligent model selection without using our inference. Provider-agnostic design - works with any models, any providers, any infrastructure.

​
Why Use This?

Use Adaptive’s intelligence, run inference wherever you want:
  • “I have my own OpenAI/Anthropic accounts” - Get optimal model selection, pay your providers directly
  • “I run models on-premise” - Get routing decisions for your local infrastructure
  • “I have enterprise contracts” - Use your existing provider relationships with intelligent routing
  • “I need data privacy” - Keep inference local while getting smart model selection

​
Request

Provider-agnostic format - send your available models and prompt, get intelligent selection back.
​
models
array
required
Array of available model specifications in provider:model_name format. Adaptive automatically queries the Model Registry to fill in pricing, capabilities, and other details for known models.
​
prompt
string
required
The prompt text to analyze for optimal model selection
​
cost_bias
number
Cost optimization preference (0.0 = cheapest, 1.0 = best performance) Default: Uses server configuration. Override to prioritize cost savings or performance for this specific selection.
​
model_router_cache
object
Semantic cache configuration for this request

​
Response

​
selected_model
object
Selected model details Complete model information for the chosen model
​
alternatives
array
Alternative models (optional) Fallback model options if the primary selection is unavailable. Each alternative is a complete RegistryModel object.
​
cache_tier
string
Cache hit information Indicates if the selection came from cache (“semantic_exact”, “semantic_similar”, or empty if not cached)

​
Authentication

Same as chat completions: 
-H "Authorization: Bearer apk_123456"

​
No Inference = Fast & Cheap

This endpoint:
  • ✅ Fast - No LLM inference, just routing logic
  • ✅ Cheap - Doesn’t count against token usage
  • ✅ Accurate - Uses exact same selection logic as real completions
Perfect for testing, debugging, and cost planning without burning through your budget.
